This is a recently released Hubble's image of the COSMOS field - part of the sky used by astronomers to study the distant universe. It contains pictures of many galaxies, some of them with redshift over 2. That means their light has been stretched by the expansion of the universe into the infrared part of the electromagnetic spectrum.
